Master Lock
This keyed padlock by Master is a solid piece of equipment, and it's a Master product. The keyed locks are very flexible to the point of a more tight fit since you can go further into the shackles. See pictures. The shackle is quite long should you have a distance to travel between handle to handle. However, great lock for a very reasonably price and it gives the place a more industry look and High Tech. We all remembered the school lockers and everyone was sporting a Master Combination Lock. Anything else was anything else. They came in all kinds of colors after the black and silver ones, and I'm thinking by now they must have plenty of exotic colors ones. I love these Master keyed padlocks because to me they are a novelty and different. Just remember, there is a key needed to open this keyed padlock. 😉

Perfect Fit
I needed an outdoor lock for a resin storage box. The other locks had necks that were too short and too thick. This lock was a perfect fit and is secure.

Good quality lock and perfect for my application.

Perfect for my garden shed as it has a long shackle and the sliding doors are always difficult to close. The long shackle makes the final closure easier. Very good lock. Would buy again
